What are the results with the Tomatis® Method?

resultats-recherche-tomatisIn addition to the positive results achieved with our clients and which have made our reputation, our method has also proven its effectiveness scientifically. The research continues to grow as the areas of application of the method are extended. Indeed, the
acoustic sensory message plays a key role in the development of the individual and as a result connects to a broad range of disorders. The scientific partners with whom we work include several public bodies (ministries, research institutes, hospitals) as well as universities, specialized associations and foundations. Their involvement ensures the objectivity and reliability of the results presented for you in a non-exhaustive overview in the following tables.
